V UNITED STATES PATENT OFFICE.

GAS MIXER.

Application filed September 18, 1923. Serial No. 663,454.

To all whom it may concern.

Be it known that 1, Farms A. GENTRY, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Gas Mixer, of which the following is a specification.

This invention relates to an attachment for internal combustionengines, the primary object of the invention being to provide novel means for supplying heated air to the charge entering the intake manifold after the charge has passed from the carburetor.

Another object of the invention is to provide a device of this character including a nozzle of a construction to be readily and easily secured to the usual internal combustion engine construction, the nozzle being such as to direct the heated air through the charge at an angle with respect to the path of travel of the charge.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangementof parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational view disclosing the attachment as installed on an internal combustion engine.

Figure 2 is a fragmental sectional View disclosing the relation of the nozzle with respect to the intake manifold.

Figure 3 is a sectional View on line 3-3 of Figure 2.

Figure 4 is an enlarged elevational view of the nozzle portion.

Referring to the drawings in detail, the reference character 5 designates the intake manifold of an internal combustion engine, which is formed with the usual flange 6 at the intake end thereof, which flange cooperates with the flange 7 formed at the upper end of the carburetor pipe 8 for clamping the nozzle of the attachment in position.

The nozzle is indicated generally by the reference character 9 and embodies a head formed with openings 10 to receive securing bolts 11 that also pass through the flanges 6 and 7 to secure the nozzle in position. A central opening 12 is formed in the nozzle, which opening registers with the intake manifold 5 and pipe 8 so that a charge passing from the carburetor which is in communication with the pipe 8 and which has been omitted in the present showing, may pass to the intake manifold in the usual manner.

A wall 13 is formed across the lower portion of the opening 12 and has a cut out portion 14: in one surface thereof, which cut out portion has communication with the bore 15 through the openings 16, whereby air passing through the bore 15 may enter the intake manifold 5, through the openings and at an angle with respect to the passage of travel of the charge from the pipe 8, to the end that the air is thoroughly mixed with the charge.

The reference character 17 designates a valve body in which is positioned a controlling valve 18 for controlling the passage of air to the nozzle proper, the communication between the valve body 17 and nozzle being made through the pipe 19.

Coiled around the exhaust pipe 20 is a pipe 21 that has one end thereof connected with the valve body 17 at 22, the opposite end of the pipe 21 being disposed adjacent to the forward end of the exhaust manifold 22, while the portion of the pipe between the coiled portion thereof and open end 28 is disposed on the exhaust manifold 22 as clearly shown by Figure 1, so that the heat from the exhaust manifold 22 will be directed to the pipe which in turn will heat the air passing therefrom.

The valve 18 is formed with an arm 24; that has connection with the rod 25 that is employed for operating the valve 18 through the medium of the connecting link 26 and arm 27 secured to the lower end of the rod 25.

It might be further stated that the upper end of the rod 25 is disposed in proximity to the steering wheel of the motor vehicle, whereby the same may be readily and easily manipulated by the person operating the vehicle.

In the use of the device the valve member 18 is operated to allow a predetermined amount of air to be drawn through the pipe 21 to increase the efiiciency of the engine and at the same time reduce the fuel consumption to the minimum.

I claim 7 In a device of the character described a nozzle adapted to be secured at one end of an intake manifold of an internal combustion engine, said nozzle including a body portion having a bore formed therein, said body portion having a cut out portion forming a compartment openingtowards the for- Ward portion of the body portion, and definin an u 3 )er artitionin wah said bod p b y portion havlng a plurality of openings estab- .thr0ugh,,at a point adjacent to the compartment.

In testimony that I claim the foregoing as-my own, I have hereto affixed my sigmv ture in the presence of two Witnesses.
